LOGOKIEGTIVE DRIVING-BOX.

To aZZ whom, it may concern:

Be it known that I, FRANCIS J. Conn, of Schenectady, in the county ofSchenectady and State of New York, have invented a certain new anduseful linprovement in Locomotive llriving-lloxes, of which improvementthe following is a specification.

The driving hex construction which is ordinarily applied in locomotivesconsists of fast, thereby occasioning a pound or knock, which indicatesthat the bearing does not fully set forth.

an integral body of cast iron or steel, in which a semi-circularly boredbearing is firmly fixed, usually by being forced in place by hydraulicpressure. The vertical. bearing pressure resultant upon the weight ofthe supported load is ordinarily limited to about 200 pounds per inch ofprojected area, and, of course, acts in a vertical direction. Thehorizontal forces resultant upon the pres sure of the steam upon thepiston, acting through the leverage of the crank pins, driving wheels,and axles, are considerably greater than that of gravity. Upon a combination of these forces, there is produced a resultant of about 30degrees from the horizonta but the intensity of the pressure due to thehorizontal forces is much greater than that of the portion of the weightof the locomotive which is supported on the journal. lhe natural resultof this condi tion is to wear the boxes horizontally very fit closely onthe journal, in a horizontal plane. l v hen this occurs, 1t is usuallynecessary to remove the wheels from the lcomotive and rebore theb'rasses, cutting away much of the top hearing.

The object of my invention is to provide a construction in which thebearing surface which opposes the horizontal forces may be materiallyinci'eased. as to the extent of being more than doubled, and meansprovided for'taking up the wear, and in which the bearin 's can bereadily removed for renewal, without taking the wheels from under thelocomotive.

The improvementclaimed is hereinafter In the accompaiiying drawings:Figure 1 is a view, in perspective, of a locomotive pedestal, fittedwith a driving box illustrating an embodiment of my invention; Fig.2,- aplan or top view of the driving box; Fig. 3, a view, partly in outer endelevation and partly in vertical transverse section on the line a of a;Fig. at, a view, partly Specification of Letters Patent.

Referring first to Figs. 1 to 9inclusive, my invention is illustrated as applied in a driving box whichis fitted, with the capacity of relative vertical movement, between ashoe, 1, and a wedge, 2, which is operated by a screw, 2, in alocomotive frame pedestal, the jaws, 3, 3, of which extend from an.upper'frame rail, l, to a lowerframe rail, 5. The portion of the weightof the locomotive which is supported by the journal, (3, of-the'drivingaxle on which the driving box rests, is applied to the top of thedriving box through a springsaddle,-7, which straddles the upper framerail, and supports a driving spring, which. is not shown, in the usualmanner.
